Ecology, Behavior and Life History
Most Bos species have a lifespan of 18–25 years in the wild, with up to 36 being recorded in captivity. They have a 9–11 month gestation, depending on the species and birth one, or rarely two young in the spring.
Most species travel in herds ranging in size from 10 members into the hundreds. Within most herds, there is one bull (male) for all the cows (female). Dominance is important in the herds; calves will usually inherit their mother's position in the hierarchy.
They are generally diurnal, resting in the hot part of the day and being active morning and afternoon. In areas where humans have encroached on the territory of a herd, they may turn nocturnal. Some species are also migratory, moving with food and water availability.

Famous quotes containing the words behavior, life and/or history:
“Children, randomly at first, hit upon something sooner or later that is their mother’s and/or father’s Achilles’ heel, a kind of behavior that especially upsets, offends, irritates or embarrasses them. One parent dislikes name-calling, another teasing...another bathroom jokes. For the parents, this behavior my have ties back to their childhood, many have been something not allowed, forbidden, and when it appears in the child, it causes high-voltage reaction in the parent.”
—Ellen Galinsky (20th century)
“One reason writers write is out of revenge. Life hurts; certain ideas and experiences hurt; one wants to clarify, to set out illuminations, to replay the old bad scenes and get the Treppenworte said—the words one didn’t have the strength or ripeness to say when those words were necessary for one’s dignity or survival.”
—Cynthia Ozick (b. 1928)
“Classes struggle, some classes triumph, others are eliminated. Such is history; such is the history of civilization for thousands of years.”
—Mao Zedong (1893–1976)
